Ecological Systems and Devices Annotation << Back Classification of urban reservoirs by using methods of cluster analysis V.A. Shabanov A.V. Shabanova In the work classification of urban reservoirs of the city of Samara was carried out by methods of cluster analysis on the complex of hydro-chemical indicators (nitrate nitrogen, nitrite, ammonium, total iron, surfactants, oil products, dry residue, chlorides, sulfates, etc.). For the assessment of similarity of water ponds by hydro chemical indicators were calculated correlation coefficients, the lower and upper values of all the bivariate correlations for the probability of 0,95. It was shown that for nine objects the differences in the hydrochemical indicators are insignificant. According to the indicators characterizing water pollution (oil products, surfactants) were identified two groups of similar objects. The obtained results make it possible to divide into groups urban water bodies on a set of signs, which makes it possible e to develop for each group its optimal strategy of water quality management. Keywords: urban water body; cluster analysis; hydrochemical indices; oil products, management. Contacts: E-mail: sgasu@sgasu.smr.ru E-mail: moineau@yandex.ru Pp. 67-72.
